That's the appeal of conservativism. If you are a member of the in group, you are good, and anyone who isn't in the group is bad. That's all the justification a conservative needs to say or do anything that benefits the conservatives in the group.
It's not a contradiction at all. When it serves them to argue you need thirty 5.56 rounds, a silencer, and a bump stock to hunt quail or whatever, then that's the argument they make. When it is best to argue that their assault-themed hunting rifles will help them overthrow the government, that's the argument.
When it helps them to push moral wedge issues to lather up their small minded constituents, they will promote their credentials as the last bastion of moral authority in a world filled with demons. When one of those demons rises to be the leader of their party, they fall in line and claim he's the fucking messiah.
Those arguments aren't contradictory or hypocritical, because when they make them, they are benefitting themselves. Previous statements or positions are like farts in the wind. When they criticized government handouts, it was correct because the criticism helped them get elected, and spending less on social programs let them spend more on benefitting themselves. When they accepted government handouts, it was correct because it benefited themselves.
See how easy this is? Rational people are often confused, and assume there must be some Olympic level mental gymnastics going on inside of the mind of a conservative. It's not that complicated, and there isn't hardly anything going on. That's the appeal. You don't have to think, you don't have to remember, and you owe nobody an explanation. You are right because of who you are and therefore anything you want to do or say is righteous. Just don't go against the in-group.
